## Long description

The Synology DDR4 4GB 2666MHz memory module is a compact SO-DIMM designed to expand system memory in compatible NAS units and small form-factor computers. This 4 GB DDR4 module operates at a clock speed of 2666 MHz and uses a 260-pin SO-DIMM form factor with a 1.2 V operating voltage. It provides additional volatile memory to improve multitasking performance and data handling in environments where modest capacity increases deliver smoother operation.
Advantages
This Synology memory module offers reliable compatibility with supported devices and stable operation at standard DDR4 voltage levels. The 2666 MHz frequency supports responsive memory access for common NAS workloads and light server tasks. Its SO-DIMM form factor is suitable for compact systems, conserving space while increasing available RAM. The module’s conservative capacity of 4 GB makes it a straightforward option for incremental upgrades without overprovisioning.
Suitable for
Home or small office NAS systems requiring additional memory
Compact desktops and mini-PCs with 260-pin SO-DIMM slots
Light virtualization tasks and basic file serving
Systems needing a low-voltage DDR4 upgrade (1.2 V)
Key specifications
Capacity: 4 GB
Memory type: DDR4
Clock speed: 2666 MHz
Form factor: 260-pin SO-DIMM
Operating voltage: 1.2 V
How to use
Power off the device and disconnect it from mains power before installation. Open the device chassis or access panel to reach the memory slot. Align the module’s notch with the module slot and insert the SO-DIMM at an angle, then press down until the retention clips engage. Reassemble the chassis and power on the device. Verify that the system recognizes the additional 4 GB in the firmware or operating system memory information screen. Follow the device manufacturer’s instructions for static handling and warranty considerations.
Usage recommendations
Check the target device’s memory compatibility list and maximum supported memory per slot before purchase. For optimal performance, match frequency and voltage with existing modules where possible and install modules in recommended slot configurations. If the system uses ECC or specific memory requirements, ensure the module type is supported by the device.
